The drawings representa glass jar with a glass cover; but both maybe made of earthenware or'metal, or the vessel may be made of metal wit-ha glass or earthen cover, or vice versa. The neck of the vessel is made flat at the top for the reception of the india-rubber gasket a, by which the sealing is to be effected,
